Main functions

• Can be operated indoors with computers, can be operated alone in the field

• Long-term continuous monitoring of photosynthesis changes in multiple samples in the field

• Can measure fluorescence induction curves, fast light curves (powerful curve fitting function), quenching analysis, dark relaxation analysis

• Field digital acquisition MONI-DA can automatically record data, store with microSD card, powered by solar energy or built-in battery

• All outdoor parts are waterproof

• One MONI-DA can connect 1-7 measuring heads at the same time (3 or 4 recommended configurations)

Measurement parameters

Fo, Fm, F, Fo’, Fm’, Fv/Fm, Y(II), qP, qL, qN, NPQ, Y(NPQ), Y(NO), ETR, PAR and temperature, etc.

Application areas

Long-term continuous monitoring of the photosynthesis of plants, or conduct routine modulation fluorescence measurements with a computer.It is especially suitable for long-term ecological positioning monitoring, agricultural and forestry meteorological forecasting, guiding irrigation decisions, and building automated greenhouses.

Main technical parameters

Measured light: Blue LED, 455 nm.

Actinic light: Homology to the measurement light LED.The maximum continuous light intensity at the leaf clamp is 1500 μmol m^-2yes^-1.

Saturation pulse: Homology to the measurement light LED.Maximum saturation flash intensity at leaf clamp 3500 μmol m^-2yes^-1.

Signal detection: PIN-photodiode with long pass filter with selective phase lock amplifier.

Purchase Guide

1. Land version-offline version (both online functions)

System composition: digital (land version), computer adapter box, measuring head (land version), 10m cable, software, computer (not included in standard)

Note: MONI-DA can connect 7 measuring heads, and the memory card is external, making it easy to retrieve and download data

MONITORING-PAM diagram

2. Underwater version-offline version (both online functions)

System composition: digital feed (underwater version), computer adapter box, measuring head (land version), 10m cable, software, computer (not included in standard)

Note: The configuration of the underwater version is similar to that of the land version, but the digital processing, the probe and all cable interfaces have waterproof functions.MONI-DA/S can connect 7 measuring heads, the memory card is built-in and cannot be retrieved. Use the command to download data.

3. Land version-online version

System composition: computer adapter box, measuring head (land version), 10m cable, software, computer (not included in standard)

Note: MONI-SET3 can connect 3 measuring heads, MONI-SET4 can connect 4 measuring heads

Multi-probe example

4. Underwater version-online version

System composition: computer adapter box, measuring head (underwater version), 10m cable (recommended), software, computer (not included in standard)

Note: MONI-SET3 can connect 3 measuring heads and MONI-SET4 can connect 4 measuring heads.The configuration of the underwater version is similar to that of the land version, except that the probe and all cable interfaces are waterproof, but the adapter box is not waterproof.
